Description

one

There are known devices for handling rolls of a quarto stand, and a lifting platform with a lifting drive thereof. A mobile trolley with clamps and pushers is mounted on the platform. The grippers are made in the form of a folding hook pivotally mounted on a trolley.

The described device differs from the known ones in that the claws and pushers are mounted on a common rotary frame, freely mounted on the vertical hinge of the trolley. This ensures the self-installation of the cart when moving the rolls in the process of transfer.

FIG. 1 shows the described device, a general view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. 2

The device comprises a base plate I, levers 2, a lifting platform 3 located on the levers and a hydraulic cylinder 4 lifting platforms, pivotally mounted on the plate. The rod of the hydraulic cylinder 4 is fixed in the common hinge of the 5 levers 2. The levers are pivotally mounted in the supports 6 and 7 of the platform and plate, and the supports 7 from the side opposite to the stand are movable.

On the platform 3 there is a mechanism 8 for moving the overloaded work and support rolls, which is equipped with a movable carriage 9 with a drive for moving it. The drive is made in the form of a hydraulic cylinder 10 rigidly mounted on the platform 3 and rotatably mounted on its rod.

gear shaft And containing a central gear 12 and two side gears 13. Each of the gears engages with rails 14 and 15, while the gear 12 is engaged with the rail 15 mounted on the movable carriage 9, and the side gears 13 with the rails mounted on the platform 3. Rack mechanism 8 provides movement of the movable carriage 9 by an amount greater than the stroke of the hydraulic cylinder

10 drive rolls move i - | - 1 times, where i is the ratio of the diameters of the central and side gears.

For coupling the trolley 9 with the tides 16 and 17 of the rolls during transfer on it

Mounted grippers 18 and 19 support and work rolls, and for pushing the rolls into the cage - pushers 20 and 21. Pushers and grippers are mounted on a common frame 22, freely mounted on a vertical hinge on the trolley.

For transferring the work rolls and the upper support roll, the platform 3 rises with the stem of the hydraulic cylinder 4 to the upper position, while the levers 2 are mutually rotated

in the hinge 5, which moves upwards.

Then the rod of the hydraulic cylinder 10 of the mechanism for moving the rolls is carried out nepeiMcchen gear shaft 11, which also receives a rotational movement, as the side gears 13 do not rotate the fixed rails 15 mounted on the platform 3. In this case, the central gear 12 also rotates and moves, moves the rack 14 and the trolley 9 in the direction of the working stand.

After the trolley is led to the rolls, the corresponding grippers 19 and 18 throw on the side of the work pillows or support rolls and, when the trolley moves towards the service side, the rolls roll out onto the guide platforms 3, where they are replaced with new ones. New rolls pusher 1 20 and 21 when

Moving the trolley to the plant in the cage. The transfer of the lower support roll is carried out in a similar manner when the platform 3 is lowered.

Subject invention

Equipment for transferring rolls to a quarte cage, containing a lifting platform with a drive for it, movable, mounted on the platform, a trolley with hooks and bolts, characterized in that, in order to self-install the cart when moving the rolls during the handling, the hooks and pushers are mounted on a common swivel frame, freely mounted on a vertical hinge trolley.
